GEORGE B. BASSETT, OF BUFFALO, NE\V YORK.

- WATER-METER;

SPECIFICATION forming part of Letters Patent N 0. 608,168 dated August2, 1898. Application filed December 30, 1896. Serial No. 617,497. (Nomodel.)

T0 all whom it may concern.-

Be it known that I, GEORGE E. BASSETT, a resident of Buffalo, in thecounty of Erie and State of NewYork, have invented certain new anduseful Improvements in Water-Meters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. r This invention relates to improvements inwatermetors, and more particularly to disk water-meters of that class asshown in Letters Patent No. 501,203, granted to me on the 11th day ofJuly, 1893.

The objects of my present invention are principally to improve theconstruction and arrangement of the disk and disk-chamber and otherpoints in the construction of these meters for the purpose of reducingthe cost of manufacture, increasing the durability and efficiency, andother advantageous results.

In the drawings, Figure 1 is a central vertical section of my improveddisk and diskchaniber. Fig. 2 is a horizontal section of thedisk-chambcr, showing a top view of my improved disk placed in a levelposition for convenience of illustration. Fig. 3 is a side view of myimproved disk, with the web shown partly in section. Fig. 4 is a detailview.

The disk-chamber in use sits in an outer surrounding case, on which ismounted an indicator. The outer case and indicator, not forming a partof this invention, are not shown in the drawings, but may be of anyconvenient form, as shown in the aforesaid Letters Patent No. 501,203.

Referring to the drawings, the disk-cham her is formed of two parts 1and 2, held to- In the spherical side wall of part 1 are located theinlet and outlet ports 5 and 6, between which is permanently secured thediaphragm or partition 7. The interior faces of the upper cone or end 8and the lower cone or end 9 are each made with recesses 21, betweenwhich rigid unyielding radial ribs 22 are disposed, andat the apex ofeach is a spherical socket forming bearings for the ball of the nutatingmeasuringdisk.

In the measuring-disk one side of the ball and the Web are formed in onepiece 10, which may be cast, pressed, or machined out of metal, and towhich the other side ll of the ball, which may be formed of anon-metallic substance, as hard rubber, is fastened by tened to shaft 17and engages intermediate gear and pinion 19, which rotates on pin 20,

permanently fastened in top of part 1 and engages the stuffing-boxspindle and indicator. (Not shown.)

In both sides of the disk-web are formed the recesses 21, between whichare the radial ribs 22, that come in or nearly in contact with cones 8and 9 and in line with the ribs 22 thereon, thus forming with therecesses 21 a water-packing between the web and cones. Another object ofthe ribs 22 is to strengthen the disk without greatly increasing itsweight, and another object of the recesses 21 is to lessen the weight ofthe disk without greatly decreasing its strength. A still further objectof the recesses 21 21 and ribs 22 22 is that they very materially lessenthe liability of foreign substances, as sand or gravel, catching betweenthe web of the disk and the cones 8 and 9 and blocking the action of thedisk. The sliding motion of the diskweb on the cone is only aboutone-sixteenth of an inch, and by making the ribs a little blunt theapparatus would operate properly.

At 23 in Fig. 3 a portion of the disk-web is cut away, making a sectionshowing the recesses 21 on one side of the web coming opposite the ribs22 on the other side, making a very light yet strong construction of thedisk-web.

In the disk-Web is out the hole 24: and the radial slots 25 and 2G, inwhich is received the diaphragm 7, the edge of the disk-web at slot 25bearing against the part of the diaphragm next to the disk-ball, and theedge of the disk-Web at slot 26 bearing against the part of thediaphragm next to the outer wall of the disk-chamber, thus forming aninner and outer bearing for the disk-web on the diaphragm 7, and therebylessening the wear and liability of the disk and diaphragm to becomecramped and also at the same time affording an outlet through hole 24for the water that may become trapped in the corners between thedisk-web, diaphragm 7, and cones 8 and 9.

The disk is provided with peripheral ribs a, whereby to prevent toogreat a leakage through the ends of the radial recesses.

It is important to the practical working of the device that the diskshall have as wide an edge as possible where it comes into contact withthe spherical wall of the disk-chamber,

and the ribs a afford such wide bearing-faces for the disk.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a disk water-meter, the combination with a disk-chamber having itsend or ends provided with a multiplicity of recesses with rigid orunyielding walls, of a disk having its surface also provided with amultiplicity of on the disk-chamber being adapted to coin- 4o cide orcome opposite and in contact or nearly in contact with each other attheir outer surface.

3. In a disk water-meter, the combination with a disk-chamber the end orends of which have an unyielding irregular surface, of a disk having anunyielding irregular surface on both sides, the depressions in one sideof said disk coinciding with or coming opposite of the projections onthe other side of said disk.

4. In a disk Water-meter, a disk having an unyielding irregular surface,and a peripheral rib or flange.

5. In a disk Water-meter a disk having a peripheral rib or flange and anunyielding irregular surface on both sides, the depressions on one sidecoinciding with the projections on the other side of said disk.

6. In a nutating-piston water-meter, the combination of a disk-chamberand a disk the end or ends of the chamber and the faces of the diskhaving recesses and radial ribs, the disk having its edges full and notcut away by said recesses.

7. In a disk water-meter, the combination of a disk-chamber and a disk,the end or ends of the chamber and the disk havingradial recesses andribs, and the disk having periph eral ribs.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
